Yes, the fan blades were not reversible as such due to how they were molded and mounted. However, the manufacturer (Flex-a-lite) in this instance does supply just the fan blades in the opposite orientation. If you look at the photos it will probably help explain it. I think I still have the other blades too. Asa Jay Quoting Forest Goodhart <forestg@att.net>:
Asa, You should have been able to just remove the blades and turn them around. That was the directions include when I installed Hayden fans. Maybe not all brands will reverse though.

So, when installing the Fluidyne radiator in my Pantera, I decided to mount the radiator in a slightly tilted forward position and mount the fans on the back instead of the front.
This was going to work well except the twin fan assembly I had didn't have the proper vane curve on the fan blades to work from a puller direction. What I had to do was buy new fan blades and swap them out. You can see some of that on these pages, mid-way down:

It all worked out well in the end and I never had any overheating issues. Some folks have just as good operation with rear facing pusher fans mounted to the front of the radiator. Either way should work fine but you'll want to make sure the curve of the blades is proper for the direction the fans will turn, otherwise they won't push or pull as much air.

WOULD SOMEONE PLEASE START A THREAD ABOUT OVERHEATING AND FAN ROTATIONAL DIRECTION THEORIES????
